Psychiatry of Old Age is a specialty that provides a service to those who develop mental illness over the age of 65. Mental illness in older people is common and often has a complex or multi-factorial cause. Old Age Psychiatrists therefore provide a service in general hospitals, at community clinics, in patient’s own homes, and in nursing homes. Old Age Psychiatrists work as part of a multi-disciplinary team that may include mental health nurses, clinical psychologists, occupational therapists, and social workers. In addition, Old Age Psychiatrists work closely with their colleagues in general hospital departments including medicine for the elderly, neurology, neuropsychology, neuroradiology, and in primary care.
